Everyone is caught up on the 13 seconds but when I watched the game again what really stood out was the Chiefs potentially blowing it instead. On 4th down Ingram blows past the right tackle and Josh somehow evades him and a few others on a scramble for the first. Then shortly after that Josh converts a long 4th down for a td. Josh was dialed in but I don't know how the Chiefs allowed this. For this particular game I do believe the Chiefs were the better team though Josh gave everything he had. Blame the Bills #1 defense for this loss in general.
The Bills failed to stop the Chiefs from getting into fg range earlier before halftime so their two minute defense clearly needs work.
